Predict the products in the following reaction:AgNO3(aq) + Na2CrO4(aq) →

A. AgCrO4(s) + Na2NO3(aq)

B. Ag2CrO4(s) + NaNO3(aq)

C. Ag(CrO4)2(s) + Na2NO3(aq)

D. Ag(CrO4)3(s) + Na(NO3)2(aq)

Answers

Answer 1

Answer: I think the correct answer from the choices listed above is option B. The products of the reaction made by silver nitrate and sodium chromate are silver chromate and silver nitrate. The chemical reaction should be written as:

2AgNO3(aq) + Na2CrO4(aq) → Ag2CrO4(s) + 2NaNO3(aq)

Answer 2

Answer:

The products obtained when 2 AgNO₃ + Na₂CrO₄ reacts is Ag₂CrO₄ + 2 NaNO₃.

What is a Redox Reaction ?

The reaction in which reduction and oxidation takes place simultaneously

by obtaining or losing an electron, the oxidation number of a molecule, atom, or ion varies.

In the question it is given that

AgNO₃(aq) + Na₂CrO₄(aq) → and we have to predict the products

So Silver Nitrate when reacts with Chromic Acid to from silver Chromate and sodium nitrate.

2 AgNO₃ + Na₂CrO₄ → Ag₂CrO₄ + 2 NaNO₃

Therefore Product B is the correct answer.

How might scientific knowledge about monoculture farming affect societal decisions? Please be sure to answer in complete sentences.Can someone please help me with this?

Answers

in monoculture farming , we produce a single species of a livestock or plant in large quantity.

Eventhough it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)

which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization

People could choose to practice organic farming, heirloom plants, or use GMOs.Governments could pass laws to limit the use of monoculture farming or require people to use alternate farming methods.

Any substance that yields a hydrogen ion when placed in a water solution is called a(n) _____.acid
base
hydronium ion
hydroxide ion

Answers

Answer : Option A) Acid

Explanation : Any substance that yields a hydrogen ion when placed in a water solution is called an acid.

According to Arrhenius theory of Acids and Bases, Acids are those substances which on dissociation in solution generates $H^(+)$ ions. Whereas a Base is a substance that dissociates in the solution to produce $OH^(-)$ ions.

Answer:

the answer is acid.

There are several ways to model a compound. One type of model is shown. A central C attached to 3 C's by 1 line each, each of the 3 C's being attached to 3 H's by a 1 line each. The central C is also attached by 1 line to a C, which is attached to 2 H's and a C by a single line each. The C is attached by 2 lines to an O ad by 1 line to another O. The O with 1 line is attached by 1 line to an H. What is the chemical formula for the molecule modeled? CHO C4H11O2 C6H12O2 C6H9O

Answers

Answer:

C6H12O2

Explanation:

The first step in accurately deducing the structure/formula of the model is to count the number of carbon atoms, hydrogen atoms and oxygen atoms mentioned in the model. This gives the molecular formula of the compound.

Next, you look at there arrangement of atoms and bonds as stated in the model, this tells us the structure of the molecule and confirms the molecular formula initially deduced.

The structure of the compound is shown below.

Answer:

Your answer would be C6H12O2

Explanation: I hope I helped you :)

In the chemical reaction below, what Is the product? C+o2 -> Co2

Answers

Answer:

CO₂

Explanation:

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

Reaction equation is given as;

C + O₂ → CO₂

In this reaction, C and O₂ are the reactants

CO₂ is the product of the reaction.

This reaction is called a combination reaction in which two species combines to give a product.
